This is a mod project that aims at restoring certain parts of older drafts of Half-Life 2 - namely, various original locations, characters and plot points that didn't make it to the retail version. This mod is intended to provide a complete game experience; rather than restoring disparate bits and pieces, the team instead aims at building a complete and stylistically coherent world by drawing inspiration from many original concepts and drafts provided by Valve in their book Raising the Bar. This naturally involves filling some blanks and discarding some failed or played out designs. It doesn't include original levels found in the "leaked" version of Half-Life 2, and instead features brand new maps which were built from the ground up - it was decided that this was the only way to make them both stand out and be actually modern and not just modernised fix-ups. The first part of the mod features four new chapters – the Prologue, revamped Welcome to City 17, Manhack Arcade, and Kleiner’s Lab. In short, this first part comes with 11 new/reworked levels. It only requires an installed copy of Source SDK Base 2013 Singleplayer on Steam.
